Study on Post-Earthquake Corrective Repair of the Stone Archway and Stone Screen in Tiantai Mountain

Abstract:

Abstract: The Qionglai stone archway and stone screen wall are located in Tiantai Mountain, Sichuan Province. Due to the impact of the 5.12 Wenchuan earthquakes, the stone archway began to subside and tilt. The maximum settlement of the two columns in the northeast was 60mm and the vertical deviation was 42mm.The main ridge of the roof which was badly damaged was out of joint and began to fracture, shift and fragment. Other part also got damaged in varying degrees. Due to the special geographical environment, large-scale machinery cannot be put into use. Thus, we can only use small equipment and labor, take advantage of pulley block and set up a steel hoop to improve pillars with jacking and corrective method. At the time of repairment, it should follow the principle of "repair the old as not to change the original appearance" and use the original materials and follow the original process as much as possible so that the stone archway and stone screen wall can be in the original shape.
